Figure 4From: A modified liquid chromatography/tandem mass spectrometry method for predominant disaccharide units of urinary glycosaminoglycans in patients with mucopolysaccharidosesEvaluations of the effectiveness of ERT in MPS patients. The reduction of urinary GAGs after ERT in MPS I, II, and VI patients was significant (A); the reduction of DS and HS in patients with MPS I- Scheie (B), and the mild form of MPS II (C) patients after ERT was notable.Back to article page
